This is V5 changes for common spi driver for the brcmstb, nsp, ns2, cygnus
SoCs. Changes include driver for standard MSPI and accelerated BSPI blocks.
The Brodcom STB uses l2-intc where as the SoC specific interrupt handling
code has been separated in a new driver. In case of NS and NS2 SoCs it does
not have a dedicated l2 controller and the interrupts are specific to the
spi core. The drivers are organized in the follwoing way:
drivers/spi/spi-bcm-qspi.c - Common MSPI, BSPI driver
drivers/spi/spi-bcm-qspi.h - Common header
drivers/spi/spi-brcmstb-qspi.c - SoC specific wth brcm,spi-brcmstb-qspi
compatibility, does not have anything
specific for stb SoC
drivers/spi/spi-nsp-qspi.c - Implements the interrupt hooks used by
the common driver with "brcm,spi-nsp-qspi"
compatibility
Changes in V5:
- Added additional description in the binding documentation non MSPI and BSPI SoC IP
- Split commits for MSPI spi driver and accelarated BSPI driver used for accelerated
flash reads
- Removed any parsing of transfer structures for commands
- Other code cleanup for readability
- Kept the interrupt handling code in separate driver, since hardware abstraction and l2
controller driver in software do not exisit certain SoCs
